BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a method, system, and article of manufacture for developing software components and capability testing procedures for testing coded software component.

2. Description of the Related Art

An integrated development environment (IDE), also known as an integrated design environment and integrated debugging environment, comprises a computer program or development tool that assists computer programmers in developing software. IDEs normally consist of a source code editor, a compiler and/or interpreter, build-automation tools, and (usually) a debugger. Sometimes a version control system and various tools to simplify the construction of a GUI are integrated as well.

During program development, developers of program components, comprising the functions that perform and implement the product operations defined during a high level design phase, may develop tools and other programs to test the components they are developing. Different developers working on different components may separately develop different test programs to test their components. Component developers often develop unit tests that test their specific functions without considering the effects of their component operations on other components. For instance, in the “extreme programming” paradigm, component developers test their components while coding the component. Each component developer may create different test modules. In many situations, component developers do not leverage the testing efforts of others.

Other software development techniques include the use of unit test tools, such as Jtest®, C++ test, Ctest. (Jtest is a registered trademark of Parasoft). These unit test tools test individual routines. Traditional unit test methodology performs low level verifications of the code operations, such as interaction with memory, stack, input/output behavior, boundary condition, and exceptions. The Rational Unified Process (IRUP) is an iterative software development process providing an adaptable process framework, intended to be tailored by the development organizations and software project teams that will select the elements of the process that are appropriate for their needs. The RUP seeks to develop software iteratively, manage requirements, use component-based architecture, visually model software, verify software quality, and control changes to software.

There is a need in the art for improved techniques for developing software and capability testing procedures for testing software components and their interaction.

SUMMARY

Software components and capability testing procedures for testing coded software components are developed by generating documentation describing capability test test cases used to test components implementing operations of the software product. Capability test programs are generated implementing the capability test test cases for the components, wherein component developers use the capability test programs to test components during the development and coding of the components. Documentation is generated describing component abstract test cases incorporating information on capability test test cases. Component test programs are generated implementing the component abstract test cases for the components and utilizing capability test programs, wherein each component test program tests one component for at least one test case specified in the component abstract test case documentation for the component. The capability test programs and component test programs are stored in a shared repository accessible to multiple developers and testers of the software product. A software development program is deployed to the developers and testers developing the software product to enable the developers and testers to execute groups of component test programs in the shared repository to test the components during different phases of the development of the software product.

DETAILED DESCRIPTION

FIG. 1 illustrates an embodiment of a software development computing environment. One or more developer clients 2 communicate with a server 4 over a network 6. A developer client 2 includes component files 8 being developed and coded by the developer user of the developer client 2 system. A component file 8 implements one or more functions of a software product being developed. The developer client 2 further includes a software development tool 10, such as an integrated development environment (IDE) tool, also known as an integrated design environment and integrated debugging environment, which comprises a computer program or development tool that assists computer programmers in developing software. The software development tool 10 may consist of a source code editor, a compiler and/or interpreter, build-automation tools, scripting program to create test cases, and a debugger. The source code editor tool enables the developer, tester and others involved in the software product development to code the components of the software product and create test programs to test the components and the interaction of the components. The test programs may be coded as scripting programs or other types of programs known in the art.

The server 4 includes a software development manager 12 program to manage access and publication of the components 14, capability test programs 36 implementing test cases for the components 14 being developed by multiple developers using the client developer 2 systems, component test programs 16 implementing test cases for the components 14 used by testers to test the component programs 16, system test programs 18 implementing test cases testing the interaction of multiple components 14, and the source code 20 of the software product in a shared repository 22 accessible to the client developer 2 systems. The software development manager 12 may provide services to the client developer 2 systems to allow the developers to check-in and check-out components 14, test programs 36, 16 and 18, the source code 20 and to control versioning and changes. In alternative embodiments, the check-in, check-out and versioning features of the software development manager 12 may be implemented locally in the software development tools 10 of the client developer 2 systems. The test programs 16, 18, 36 may comprise script programs or other types of code to implement the test cases for components 14.

The developer clients 2 that communicate with the server 4 may comprise suitable computational devices known in the art, such as servers, desktop computers, workstations, mainframes, hand held computing devices, telephony devices, etc. The server 4 may comprise a suitable server system known in the art. The shared repository 22 may be implemented in a storage system known in the art, such as a storage system including a plurality of storage devices, e.g., interconnected hard disk drives (a Redundant Array of Independent Disks (RAID), Just a Bunch of Disks (JBOD), Direct Access Storage Device (DASD), disks connected in a loop configuration (serial loop, Fibre Channel Arbitrated Loop), a single storage device, a tape library, an optical library, a network attached storage (NAS), etc. The network 6 may comprise a Wide Area Network (WAN), Local Area Network (LAN), Storage Area Network (SAN), wireless network, the Internet, an Intranet, peer-to-peer network, etc.

FIG. 2 illustrates an embodiment of a flow of the software development process performed by multiple software developers in a distributed software development environment. At start 50, the developers, architects and others engage in the high level design 52 to determine the operations of the user interfaces (e.g., graphical user interface (GUI) panels, command line interface lines, etc), messages, etc. of the software under development. The result of the high level design 52 phase may be documented in high level design documentation 22. From the high level design phase 52, the developers proceed to the low level design phase 54 where the developers determine components (e.g., functions, subroutines, etc.) to implement the operations determined in the high level design 52 phase and write prototype code, determine algorithms and modules, etc. The results of the low level design phase 54 may be documented in low level design documentation 24. As the developers engage in the low level design 54, they may also be involved in capability test (CT) planning 56 to provide planning for the test cases that will be used to test the individual components and interactions of the components. At the capability test (CT) planning 56 phase, developers, testers and others may work together to provide up-front planning and structure to the capability testing. The results of the determined capability test planning and test case scenarios may be documented in capability test (CT) documentation 26. Further, during different phases of development, test case scenarios documented in the capability test (CT) documentation 26 may be updated to reflect changes made to components and the design.

The CT documentation 26 may specify test cases for the components identified during the low level design phase 54 and for the interaction of the components, which are documented in the low level design documentation 24. The test cases may consider different configurations under which the components may execute, such as different system settings, file system attributes, etc. The test cases may further specify test component operations under error conditions, such as invalid settings, to validate the messaging operations of the components. The test cases may further consider interactions of the components with client level, server level and other third party software. The test cases may test the user interface operations. The test cases seek to test scenarios based on developer knowledge of the inner-workings of the component code to stress critical and complex logical areas, exception handling, and special conditions. Certain of the test cases may perform exception handling by triggering conditions not expected under normal processing (e.g., session failure, unexpected response from a server or the operating system, etc.). Other test cases may test memory operations by running a leak test on the memory trace on the most frequent code paths.

The documentation 22, 24, and 26 may be provided to developers and testers to consider when coding components and test programs 16, 18, 36 during the phases 58, 60, and 56, respectively. During the component abstract test case phase 58, the testers (or developers) may create component abstract test case documentation 28 providing information on test cases that may be used to test the components. The testers determining component abstract test cases may consider test case scenarios documented in the capability test documentation 26 by the component developers. During a system abstract test case phase 60, the developers, testers, and others may create system abstract test case documentation 30 indicating different test cases for interactions of multiple components to test component integration. When testing the interaction of components, the test cases may define output from certain components that provides input to other components. In different test cases, different inputs are provided to the components to produce different outputs.

The testers determining system abstract test cases may consider test case scenarios documented in the capability test documentation 26 by the component developers and component abstract test case documentation 28. The test case documentation 26, 28 and 30 provides test case information to encourage developers, testers and others to utilize the same information, concepts and tools to facilitate consistency in their coding and testing. The documentation may be considered and reused at different phases of development, such as phases 52, 54, 56, 58, 60, 62, 64, 66, and 68. Developers may proceed to the design and planning phases, such as phases 54, 56, 58, 60, and 62 when creating new components or modifying and debugging components in order to update the information on capability and other test cases to test the new or modified components. Further, the software development tool 10 may provide access to the documentation 22, 24, 26, 28, and 30.

The test cases specified during capability test planning 56 and component 58 and system 60 abstract test case phases may specify different combinations of attributes, input and other system variables to provide to a component to test the component according to the provided values. A test case comprises a basic unit used to define a distinct set of attributes, such as environment, e.g., operating system, settings, and input values that may be provided to a component to test the operation of component using the attributes and input values defined for the test case. The system abstract test cases define different attributes and input values to provide to multiple components to test the interaction of a subset of components or all the components of the software product. The test cases may further specify expected outcomes for the different test cases.

Multiple developers and other participants in the software development process may consult the capability testing (CT) 26, component abstract test case 28, and system abstract test case 30 documentation during all phases of the development process to facilitate integration of the capability testing programs developed by the different participants in the development process. Further, when documenting the test cases, developers may decide to modify the low level design 54 documentation based on observable test results

In the coding phase 62, component developers code the components 14 implementing the functions and components specified in the low level design documentation 24. During the coding 62 phase, the component developers may engage in a capability testing (CT) automation 64 phase by developing capability test (CT) programs 36, e.g., script programs, tools and other code, to test the components they are coding. Testers may participate in a component test program phase 66 and a system test program phase 68. During the component test program phase 66, component developers, testers, etc. may consult the component abstract test case documentation 28 and capability test (CT) planning documentation 26 to develop component test programs 16 to test the components for the specified component abstract test cases. Each component test program 16 may implement one or more test cases for one component 14. During the system test program phase 68, the tester, developer, etc. may consult the CT 26 and system abstract test case 30 documentation to develop and code system test programs 18 to test the interaction of multiple components for different system abstract test cases. The testers may consider and utilize the tools and scripts the developers created to test their components during the CT automation phase 64. For instance, the testers may incorporate information on the tools and scripts the developers created as part of the CT automation phase 64 to generate the component 28 and system 30 abstract test case documentation and to create the component 16 and system 18 test programs to further test the code.

At an execution phase 70, the developer or tester may use the software development tool 10 to select one or more capability test programs 36, component 16 and/or system 18 test programs to execute to test one or more of the components. In one embodiment, a plurality of test buckets 32 may be defined in the shared repository 22, where each test bucket 32 identifies a plurality of capability test programs 36, component 16 and/or system 18 test programs. The developer may use the software development tool 10 to select one of the test buckets 32 and then automatically execute all the programs 36, 16, and/or 18 defined in the test bucket 32. During the execution phase 70, the executed test programs 36, 16 and 18 may validate new functions and perform disruptive testing to identify side effects of new code on existing and previously tested components.

In a tracking phase 72, the results of executed programs 36, 16 and 18 may be displayed to the user of the software development tool 10, such as the testers or developers. Further, information on the test results may be maintained in tracking documentation 34 to enable tracking of defects discovered when executing the programs 36, 16 and/or 18. The developers may access the stored tracking documentation 34 during different phases of the development of the software product and return to the coding phase 62 and use such information to modify the component coding to correct defects. After correcting defects in the coded components 14, the developers and/or testers may rerun the programs 36, 16 and 18 to test the changed component code 14. Further, based on the tracking results, the developers and testers may return to the low level design phase 54, capability test (CT) planning 56 phase, and component 58 and system 60 abstract test case phases to modify information, test cases, etc., and update the corresponding documentation 24, 26, 28, and 30.

With the described embodiments, upon creating new components or modifying existing components, the developers, testers, etc may update the documentation 24, 26, 28, and 30 generated during the low level design phase 54, capability test (CT) planning 56, and component 58 and system 60 abstract test case phases to reflect these changes. Further, the capability test programs 36, component 16 and system 18 test programs may be modified to reflect these changes by adding or modifying the programs 16, 18, 36. These added test programs may be executed during the execution phase 70 for error tracking and debugging of the new components. The software development tool 10 enables developers and testers to perform automated and repeated execution of the test programs throughout the development and testing of the components and a test of a deliverable software product. The deliverable software product may comprise a new version of the software product, a program temporary fix (PTF) providing fixes and preventive service for an installed software product or an Authorized Program Analysis Report (APAR)/fixtest fix providing corrective service to an installed software product.

FIG. 3 illustrates an embodiment of operations performed by developers, testers and others involved in the software product development process to implement the software development phases described in FIG. 2. Upon initiating (at block 100) the software development process, the developers, architecture designers, and testers may participate (at block 102) in the high level design phase 52 to determine overall operations and interactions of the software product and create high level design documentation 22. The developers may then engage (at block 104) in the low level design phase 54 to determine components to implement operations specified in the high level design and generate low level design documentation 24 providing information on the components for the software product. The developers, testers and others may participate (at block 106) in a capability test (CT) planning phase 56 to determine test cases and testing scenarios to test different components developed during low level design. Capability test documentation 26 is generated to reflect the test cases determined during the capability test phase 56. During the component 58 and system 60 abstract test case phases, the testers generate (at block 108) component abstract test case documentation 28 describing component test cases to test components of the software product and generate (at block 110) system component abstract test case documentation 30 describing system abstract test cases to test an integration of the components. As discussed, the testers may utilize test cases determined during the capability test planning phase 56 and capability test programs 36 provided by the developers.

The developers may use the low level design 24 and capability test (CT) documentation 26 to code (at block 112) the components during a coding phase 62. During a capability testing automation phase 64, the component developers or others may code (at block 114) capability test programs 36 implementing component test cases identified in the capability test planning phase 56. The testers may further code (at block 116) component test programs 16 during a component test program phase 58 and code system test programs 18 implementing the system abstract test cases as part of the system abstract test case phase 60 to test an interaction of multiple components 14. The capability test 36, component 16 and system 18 test programs are stored (at block 118) in the shared repository 22 accessible to the developer client 2 systems used by developers and testers of the software product. The documentation 22, 24, 26, 28, 30, and 34 may also be stored in the shared repository 22 to be accessible to multiple participants in the software development process.

The software development program 10 may be deployed (at block 120) to multiple developers and testers to enable the developers and testers to execute groups of capability test 36, component 16 and/or system 18 test programs in the shared repository 22 to test the components 14 and/or component 14 integration/interaction during different phases of the development of the software product. The developers and testers may use the software development program 10 to select and execute (at block 122) one or more capability test 36, component 16 and/or system 18 test programs to generate test results as part of the execution phase 70. The software development program 10 may store (at block 124) the test results in tracking documentation 34 to enable tracking of defects discovered when executing test programs 36, 16, and/or 18 as part of the tracking phase 72. Developers may use (at block 126) the tracked test results recorded in the tracking documentation 34 to modify component coding to correct defects. In an additional embodiment, developers and testers may use (at block 128) the software development tool 10 to select one test bucket 34 and run capability test 36, component 16 and/or system 18 test programs in the selected test bucket 34 to test components and/or component interaction.

Described embodiments provide software development tools and a software development process to facilitate sharing of information and shared development of capability testing test cases to test components 14 and their interaction. Described embodiments further provide a system to share capability test 36, component 16 and system 18 test programs with developers and testers to use to test the components they may be individually developing and testing. Further, the testing programs 36, 16 and 18 may be invoked and run at different phases of the software development process and test results maintained in tracking documentation 34 accessible to multiple developers and testers to use to determine whether their components need to be modified to fix any defects. With described embodiments, testing and test case information and test result information are made available to developers and testers at different levels of the coding and testing process to facilitate communication and cooperation, and the use of common information and tools for testing and coding. Still further, the software development tool may enable the automated and repeated execution of test programs throughout the development and test of the components and the software product delivery.
